' APPARATUS FOR WASHING CUPS, GLASSES, AND THE LIKE- Application filed January 29, 1926, Serial No. 84,627, and in Italy February 4, 1925.

This invention has for its object to pro vide an apparatus for washing and disinfecting cups, glasses and the like and is chiefly 7 characterized by the fact that said operations are effected by means of water jets thrown with force and carrying'along heavy bodies,

for instance lead or steel or brass or alumin-' ium or lass balls; said bodies, thus thrown at a big speed, strike against and clean the n walls against which they are thrown.

This invention has further for its object to provide suitable means for dischargin the water, while the balls are collected an returned into the projecting conduits, wherefrom they are again carried along by the water. v v

The apparatus forming the object of this invention is shown on the annexed drawings, in which 2 so Fig. 1 is an axial vertical section. Fig. 2 is a section on'a vertical plane displaced through 45 with respect to the section shewn in Fig 1. V a

' Fig. 3 is a section'simi'lar to Fig. 2 showing 3| on an enlarged scale the apparatus in the working position. I p A funnel-shaped-reoeptacle 1, preferably of sheetjiron, is provided with openings 2, the width of which' is lessthan the diameter of the balls30,vcontained in the receptacle. The receptacle 1 is provided with grooves 3 of. U-section and is suitably curved at its upper edge for the purpose hereinafter ex- P ad The receptacle 1 carries a central piece hung by means ofhooks 4and rin 5, 5 and constituted. by two annular mem rs 6 arranged in different horizontal planes and con nected by means of ribs 7.the lower annular ..member.having a centraloollar 8 constitutin .a funnel.

P he suspension-ring 5 is connected with the stem 9 of a valvelU arranged in a casin 11 and closing a discharge openin' provi ed in saidcasing when said va ve is raisedby means of two springs 12 and 13. The casing, 11 communicates through a. tube 14 with another casing subdivided into two compartments '15 and by means of a flexible diaphragm 16. The. upper'oom'partment 15 constitutesa pressure chamber, the lower compartment 20 containsa central conduit 1'7. fed by a wa'ter conduit through a filterlsa l The compartment 20 commumcates with a conduit 21 ending with a central nozzle 22 .with the balls are discharged against the and side nozzles 23 corresponding to grooves {3 of the receptacle 1, the conduit 21 constitutlng the central supporting pillar thereof.

The conduit 17 forms in the compartment 20 an annular chamber and communication between the latter and the conduit 17 is controlled by the diaphragm 16 the movement of which is controlled as hereinafter described by the operation of the valve 10. The diaphragm 16 'has mounted centrally therein a throttling valve 19 formed with a guide stem which extends below the diaphragm into the conduit 17 and said valve and stem have an axial passage l9 through whichcommunication between said conduit and the pressure chamber 15 is constantly maintained. Afterthe valve 10 has been closed, the water in conduit 17 Will continue to flow throu h passage 19 until the pressure on both si es of the diaphragm becomes the same, so that the weight of the valve stem on the underside of'the diaphragm will cause the latter to seat on the end of the conduit 17 and close communication between the conduit and the annular chamber 20; a

The apparatus comprises further a protectingcasing 24, a casing 25 and a sleeve 26 'arran ed at its upper part and referably of g ass. At the upper part of t e apparatus a circular spraying arrangement will e conveniently disposed and fed by a tube 27 carried by the conduit 21.

The apparatus works as follows:

When the .cup or glass rim is pressed against the supporting piece 6, 7, this latter," by means of the ring 5 causes the stem 9 of the valve 10 to oscillate, so that the valve, coming into an inclined position with respect to its seat, allows the water to esca e from the casing 11 and therefore from t e compartment 15, in which the pressure is thus nearly completely annulled.

The counterpressure being relieved from the flexible diaphragm 16, this latter is raised by the water pressure on the underside of the diaphragm and opens a free passagetothe water from the conduit 17 to the compartment 20 and conduit 21. Strong water jets are projected through the nozzles 22 agaanst the cup or the like to be washed inside the same. The water in conduit 21 also issues from the diagonallyarranged nozzles 23 into the ves 3 from which the water together outside of the cuporthe like at the mouth or rim of the latter. This.ia aceomplished by the rim of the receptacle 1 being inwardly and downwardly turned towards the moat of the cup.

I The balls 30, carried along by the Water,

are violently projected against the glass walls and fall again into the receptacle 1 and are collected at the central part thereof and brought again into circulation by the water jets. The water is collected in the casing 24 and discharged therefrom.

In this way a perfect washing of the glass is obtained and completed by a washing of the opter upper part by providing a circular 'et 2 1 In order to prevent any ball from getting behind the stem 9 thus preventing a perfect closure of the valve, the stem is provided with a plate .9 fitting in the opening of the receptacle 1 through which the stem 9 projects. Said plate expels from said openmg the balls -that may have eventually stopped therein.- I

The feeding tubes will be conveniently provided with an expansion chamber in order to damp the water hammer taking place when the water circulation is suddenly stopped after the glass has already been taken away from the supports 6, .7.
